Bhagavad Gita 18.52

viviktasevī laghvāśī yatavākkāyamānasaḥ | dhyānayogaparo nityaṃ vairāgyaṃ samupāśritaḥ ||

living in a quiet place, eating lightly, with speech, body, and mind under control, always devoted to the yoga of meditation, and taking refuge in dispassion;

Modern context

Living simply in quiet places, eating lightly, keeping speech, body and mind in check, devoted to meditation and resting in dispassion. This is a picture of a simple, focused life. It need not mean leaving society. Anyone can find quiet time, eat moderately, speak with care and meditate regularly. These habits create the conditions in which deeper understanding can grow.
